f amma Ummn TEE Aer or MARCH 3, 1883, AS AMENDED araIL' 30,1928; 370 o. e. 757) The invention described herein may be p manufactured and used'by or for the Governm ment'forgovernmental purposes, without the payment tome of any royalty thereon.

6 The subject or; thisv invention is a A gun carriage.

' generally emplaced by removing the wheel if pground orfbyfelevating the platform with re- -f 'fspecti to the axle inorder .to remove the load "from" the springs. According .-to the first.

i method thejacks are-carried by the platform while inthesecond method the jacks may be carried either by the platform or the axles.

f fIn'the gunca'rriage of this invention it is A propjose clto carry the jacks in thelwheels and V f: 'tofirst lower the axles and platform and then 0. by a continuation ofthe lowering movement f" toelevate the platformsuflicientlyto remove --*the load .from the springs, E w a h With the foregoingand other objects in 4 I View, theinventioniresides in the novel arrangement and combination of parts and in H the details'j of construction hereinafter def scribed and claimed, itbeing understood that changes, in the precise embodiment of the invention'herein disclosed; may be made withv 0inTthe scopelof what is Claimed without deflparting from thespiritof the invention.

l Referringto the drawings by numerals of -There is showna gun carriage of the four- ';wheel trailer type whoseplatform 5 carries pended on springs 7 l ;Mobile guncar'riagesi "whichare designed toconstitute semi-fixed platform mounts are,

units and lowering the platform to the tlOIlGd. within the guides 13 of the frame and A' practical". embodiment of the invention a pedestal mount 6 on whichis trunnioned the gun (not shown). The platform'is suswhich are fastened to a the axles8. v. The axles are connected to the wheels 9 55.,

by means-of jacks, the frame or pedestal 10 i H of a j ack being mounted on the. extremity of the axle and in the case of the front steering wheels this frame is held by a vertical pivot pin 11. The rack bar 12 of a jack'is posi- 6o.

at its lower endit carries a stud axle 14 for the wheel. The actuating mechanism of the jack is conventional and consists of the pin: ion 15, worm gearing '16, ratchet and pawl indicated atl? and socket member 18 for the lever 19. j i

The head 20 of the rack bar is enlarged and because of the position of the jack it is arranged to engage the platform. 7 0,

The emplacing of the carriage is accom- V plishedby actuating the j acksat eachcorner of the carriage to lower the axles and this movement is continued until the foot of each 1 jack rests on the ground. If the ground is '75.

normally level, the heads 20 of the jacks will be in proximity to the platform and .a further actuation of the jacks will cause the. heads to engage the platform and then raise it sufiiciently to remove the load from the 80. springs" In order to provide uniform stability for all around'firing, an outrigger 22 hinged ceng V trally to the platform onthe 'sides of the carriage is swung out and securedby a spade 23. 85.. In changing from the firing to the traveling position, the foregoing operation is reversed.

I claim: a

1. gun carriage including front and rear 90., axles, a jack pedestal on each extremity of the axle, the pedestals provided with a foot, and the pedestals on at leastone axle being pivoted for steering, a rack bar in each pedestal, means for actuating the rack bar, a 9 5;

stub axle on the lower portion of the rack bar, a wheel on the stub axle, and a platform suspended on the axles, having portions overlying the rack bar in position to be engaged V by the rack bar when the foot of the pedestal 7 Contacts" the ground tosuppoxttheiplatform independently of thewhee1s5 f 2.
